Researchers discover new microbe near Chilean coastal fault line (Phys.org) —A team of researchers from McMaster and the University of Concepcion are shining a light on rare sulfur-loving microbes off the coast of Chile. The group's work near coastal fault lines has identified a previously unknown type of molecule, macplocimine A, which produces valuable natural chemicals that are known to function as effective cancer therapies and antibiotics. "The search for new drugs takes many forms and routes, but one that often has success is the search for microbes," said Nathan Magarvey, a researcher with the Michael G. DeGroote Institute for Infectious Disease Research, and project leader in Chile. "The fascination of finding drugs from natural sources has long been guided by serendipity alone, but now researchers are defining genomic and metabolomic patterns that illustrate where new drugs may be found and how these drugs are made and change."

Fecal transplant pill knocks out recurrent C. diff infection Swallowing pills containing a concentrate of fecal bacteria successfully stops recurrent bouts of debilitating Clostridium difficile (C. diff) infection by rebalancing the bacteria in the gut, suggests a study being presented at the IDWeek 2013™ meeting today. Infection from C. diff bacteria is such a concern that the Centers for Disease Control and Prevention (CDC) named it one of the three most urgent threats in its recent landmark report on antibiotic resistance. C. diff sickens half a million Americans and kills 14,000 every year. Fecal transplantation typically is delivered by enema, colonoscopy (placing a tube in the colon) or nose tube and is effective in nine out of 10 patients, according to published reports. Indeed, additional research being presented at the meeting showed patients who received fecal transplantation through a tube in the nose were highly satisfied with the treatment, and said they would likely recommend it to a friend.

CDC Threat Report: 'We Will Soon Be in a Post-Antibiotic Era' - Wired Science Image: CDC The U.S. Centers for Disease Control and Prevention has just published a first-of-its-kind assessment of the threat the country faces from antibiotic-resistant organisms, ranking them by the number of illnesses and deaths they cause each year and outlining urgent steps that need to be taken to roll back the trend. The agency’s overall — and, it stressed, conservative — assessment of the problem: Each year, in the U.S., 2,049,442 illnesses caused by bacteria and fungi that are resistant to at least some classes of antibiotics;Each year, out of those illnesses, 23,000 deaths;Because of those illnesses and deaths, $20 billion each year in additional healthcare spending;And beyond the direct healthcare costs, an additional $35 billion lost to society in foregone productivity. “If we are not careful, we will soon be in a post-antibiotic era,” Dr. Out of that matrix, their top three “urgent” threats: I talked about the report’s calls for action to Dr.

100 Character Quirks You Can Steal from Me | Anthony Owens' Weblog Okay, well, I decided that I wanted to contribute and as part of my new commitment to writing more and being more involved in the writing of others, I thought that it might be neat if I can come up with a list of personality quirks or traits that someone might find useful in fleshing out a character. I mean, even though the plot is important, it doesn’t mean anything without a character that the reader can sink into and relate to. Here goes. Normal Traits/Quirks Okay, well, I said 100, but that’s only 50. Like this: Like Loading... Netflix studies piracy sites to decide what to buy 16 September 2013Last updated at 08:30 ET By Leo Kelion Technology reporter Netflix says it monitors which shows are most popular with internet pirates Netflix has revealed that it tracks piracy sites to help decide which TV series and films it should add to its online streaming service. The US firm gave Prison Break as an example of one programme it had bought as a consequence of using the strategy. Media companies have traditionally seen copyright infringement as a threat to their business. However, some programme-makers acknowledge there can be benefits. Netflix's vice president of content acquisition disclosed its use of the technique to Tweakers, a Dutch news site covering the firm's launch in the Netherlands. "With the purchase of series, we look at what does well on piracy sites," said Kelly Merryman. "Prison Break is exceptionally popular on piracy sites. "But there are many programmes that we will not buy, such as The Voice. However, he admitted that it would not dissuade everyone.

List Your Odd Personality Quirks - The Geek Culture Forums just a few things that initially came to mind: i don't use capital letters in e-mails, postings, etc., unless the item is job or school-related. i don't remember why this started, but it's been the case for years. as much as i'd love to pass it off as an attempt to emulate e.e. cummings, it's really just habit at this point. on a related note, one of my biggest pet peeves is that sort of chat-speak that uses numbers and single letters instead of words, e.g. "how r u? i m gr8!" argh. i take notes with a blue pen on light green legal-ruled paper. notes are taken in an elaborate, highly codified outline structure using the legal rule as a basepoint. unless it's pouring rain, my car windows are always open when i drive. in the summer, this isn't terribly notable, as the top of my car's usually down, anyway. in the winter, i put the heat on full blast, but the windows stay open. i always have music playing while i drive, and (yes, i'm fully aware of how annoying this is) i always sing along.

Metabolic rate and body size are linked with perception of temporal information Open Access Highlights Animals vary in their ability to perceive changes in their environment visually. Temporal perception can be quantified using critical flicker fusion (CFF). High CFF indicates an ability to perceive rapid changes in the visual field. We show that high metabolism and small body size are associated with high CFF. We argue that these findings have both ecological and evolutionary implications. Body size and metabolic rate both fundamentally constrain how species interact with their environment, and hence ultimately affect their niche. Keywords comparative analysis; critical flicker fusion; evolutionary ecology; predator–prey; temporal resolution All biological systems, from organisms to ecosystems, are shaped by universal constraints. In animal species, the limitations of sensory systems are crucial in shaping both intra- and interspecific interactions. Figure 1. This ability to perceive and react to a dynamic environment is a key behavioural and ecological trait.

Silver trumps gold in nano advance 6 September 2013Last updated at 09:21 GMT By Julie Gould BBC Radio Science Unit Silver nanoparticles have been used for their anti-bacterial and anti-fungal properties Scientists have come up with a better way to make silver nanoparticles, which are used in textiles and cosmetics. The tiny metallic particles are often used because of their anti-bacterial and anti-fungal properties - in wound dressings for example. By using organic molecules to coat the particles, the researchers made them resistant to tarnishing, which has previously limited their use. The work has been published in the journal Nature. Previously, gold nanoparticles have been more widely used because they are more stable. Now a team has developed a way to make stable silver nanoparticles on a larger scale than was possible before. These nanoparticles are even more stable than their gold counterparts. The nanoparticles were made up of 32 silver atoms arranged into a dodecahedral core.

Dick Cheney: Heart implant attack was credible 21 October 2013Last updated at 09:06 ET Former US vice-president Dick Cheney has suffered from heart problems for much of his life. Dick Cheney, the former US vice-president, has revealed that he had his heart implant modified for fear of terrorist attack. Mr Cheney's doctor disabled the heart defibrillator's wireless function in 2007 to prevent would-be assassins from interfering with it and causing a fatal heart attack. A similar scenario featured in an episode of the hit TV series Homeland. "I found it credible," Mr Cheney told CBS TV's 60 Minutes programme. "I know from the experience we had, and the necessity for adjusting my own device, that it was an accurate portrayal of what was possible,'' said Mr Cheney, who was President George W Bush's right-hand man during the "war on terror". 'Close proximity' "Implantable Cardioverter Defibrillators (ICDs) can be vulnerable to a range of electronic signals," said Adrian Culley, global technical consultant for security company Damballa.

Artificial human ear grown in lab 31 July 2013Last updated at 05:48 ET By Helen Briggs BBC News The ear made from animal tissue bends like a real ear US scientists say they have moved a step closer to being able to grow a complete human ear from a patient's cells. In a new development in tissue engineering, they have grown a human-like ear from animal tissue. The ear has the flexibility of a real ear, say researchers at Massachusetts General Hospital in Boston. The technique may one day be used to help people with missing or deformed outer ears, they believe. Tissue engineering is a growing field in medical science, where substitute organs are made in the laboratory in the hope of using them to replace damaged ones. Continue reading the main story “Start Quote This research is a significant step forward in preparing the tissue-engineered ear for human clinical trials” End QuoteDr Thomas CervantesMassachusetts General Hospital Previously the researchers had grown an artificial ear, the size of a baby's, on a mouse.
